Study of Erbium Doping Effect on Structural, Morphological and Optical Properties of Dip Coated ZnO Under Alkaline Conditions

Structure and Magnetic Properties of AO and LiFePO4/C Composites by Sol-Gel Combustion Method

“…It is mainly the vibration absorption peak of the P-O bond and the O-P-O bond [ 45 ]. The infrared vibration absorption peak of the Zn-O bond appears at about 500 cm −1 [ 53 , 54 ] and 600 cm −1 [ 55 ], indicating that there is an infrared characteristic peak of zinc oxide. In general, the vibration absorption peak patterns of the infrared spectra of six zinc oxide and lithium iron phosphate carbon composite samples with different mass ratios are basically consistent with the FTIR test peak patterns of lithium iron phosphate by Heru Setyawan et al [ 50 ], with vibration absorption peaks corresponding to lithium iron phosphate.…”

“…That is, it is antiferromagnetic when the temperature is lower than 50 K, and paramagnetic when the temperature is higher than 50 K. The six samples analyzed at room temperature should be paramagnetic, the hysteresis loop of theory should be a straight line, and the hysteresis loop area should be zero. It can be seen from the results that the hysteresis loop area is small, while the coercivity of the sample is relatively large, showing weak ferromagnetism, which may be caused by ferrous or ferromagnetic impurities after the introduction of magnesium oxide [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , ...…”

Effect of (Al, Zn, Cu, and Sr) doping on structural, optical and electrical properties of sprayed SnO2 thin films

“…Thin films of transparent conductive oxide such as ZnO [1], TiO2 [2], In2O3 [3], and SnO2 [4], are the most scientific research subjects in current applications, and the most common is SnO2 due to its large band gap (3.65 V at 300 K) [5] making it the most widely used in many applications such as a transparent electrode in photovoltaic transformers, amorphous silicon solar cells, liquid crystal display and gas-discharge display [6]. It can be deposited by a number of mechanisms such as spraying pyrolysis [7], L-CVD [8] spin coating [9], theoretically the SnO2 thin film has a low electrical conductivity because its charge carriers have low mobility as well as its low-density charge carrier [5], which leads us to dope it with many elements to improve the most important physical properties, namely the electrical and optical properties, we can mention from these elements: Zr [10], Cu [11],Sb [12]…..etc.…”
